16 Claims.

This invention relates to printing machine folders and more particularly to a mounting for a former which is situated at a position within the side boundaries of the former.

One method of mounting a former is to suspend it from bearings positioned at each end of the axis of a web guide roller so that the receiving end of the former will always remain the same distance from the periphery of the roller when the lower end of the former is raised or lowered. When space does not permit a mounting of the above type to be provided, the former may also be mounted on a fixed pivot arranged below the web guide roller. With this form of mounting, however, the receiving end of the former would not remain the same distance away from the periphery of the roller when the lower end of the former is raised or lowered.

In the present invention, a former mounting has been provided which in effect will be the same as one mounted on a pivotal support on the axis of the web roller but will be situated in a position which is remote from the roller axis. The invention is particularly adapted for use in folders where two formers are closely mounted side by side and receive the product from a single roller which condition would make it impossible to support the formers from the roller shaft and separately adjust them.

One object of the invention, therefore, is to provide an adjustable mounting for a former on a printing machine folder which will be positioned within the width of the former and remote from the axis of a web guide roller at the receiving end of the former, but will permit said former to be moved around the axis of the roller.

Another object is toprovide a slidable arcuate mounting at the upper end of a former and an adjustment for the lower end thereof which is adapted to cooperate with the slidable mounting to move the former in a path around a fixed axis.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and ar- 45 rangement of parts, and in the details of construction hereinafter described and claimed, it being understood that various changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is 50 claimed Without departing from the spirit of the invention.

The preferred embodiment of the invention is illustrated in the accompanying drawing, wherein 5' Figure 1 is a side elevational view of a former and a support therefor, and showing said former in an operative relation with a Web guide roller;

Figure 2 is a front elevational view of said former on a reduced scale, and showing the position of the supporting members at the rear and with- 5 in the width thereof;

Figure 3 is an enlarged detail view with parts broken away and part in section, looking in the direction of the arrow 3 of Figure 1, and showing an arm on the former adjustably positioned on m a portion of the support;

Figure 4 is a cross sectional view taken on the line 4 of Figure 3, and showing the adjustable connection between an arm on the former and the support; and 15 Figure 5 is a rear elevational View looking in the direction of the arrow 5 of Figure 1, and showing an actuating member for adjusting the position of the former, and a calibrated dial plate with a pointer therefor. 20

Referring to Figures 1 and 2, a standard H is shown bolted to a position of the folder frame structure l2, and has two supports l3 mounted thereon. Each support has a head It which extends beyond each side thereof, and an arcuate 5' slot i5 is provided within one face of each head.

A former H5 is provided with two arms H at the upper rear portion thereof, each of which arms has a flange i8 extending therefrom which are secured to bosses E9 on the former. An arcu- 30 ate slot 2| is provided on the inner face of each arm and two elongated slots 22 extend into said arcuate slot from the opposite face thereof.

A key 23, of arcuate formation, is adapted to engage each of the arcuately slotted portions I5 5 and 2! when the arms I? are placed in a mounting position on the head M of said supports l3. Threaded studs 2 pass through the elongated slots 22 and openings 26 in said key, and screw into tapped openings 25 in the support heads [4, 40 by which means the arms H are clamped in an adjusted position on said supports.

Directly above the supports I3 is a web guide roller 26, which is shown in an operative position in relation to the upper or receiving end of the former l6.

At the lower rear end of said former a lug 21 is shown mounted on a boss 28. A screw 29, having ahead 3| thereon, is screwed within a bushing 32, and said bushing is rotatably mounted within a cross bar 33 of the standard I I. Said screw head SI and lug 2? onthe former are joined by means of a link 34, therefore any motion imparted thereto by the adjustment of the screw 29 will adjust the position of the former. A 001- lar 35 is secured to one end of the bushing 32 which extends outward from the face of the cross bar and has openings 36 therein for a wrench or other tool to be inserted, by means of which the same may be rotated to move the screw forward or rearward. After an adjustment of the screw is made, a lock nut 31 on the screw 29 is tightened against the collar 35 to lock the screw in its adjusted position. Also operable with said collar 35 is a pointer 38 which is secured to a shoulder on the collar and is movable with said collar when an adjustment is being made. A plate 39, secured to a raised pad 4| on the crossbar 33 has calibrations thereon which cooperate with the pointer 38.

It is to be particularly observed that the supports l3 are positioned directly under the web guide roller shown in Figure 1, and also are psitioned wholly within side boundaries or width of the former as shown in Figure 2. In order to provide an adjustment for .the former which will permit the upper edge of same to move in an evenly spaced relation to the peripheral surface of the guide roller, the arcuate slots l5 and 2| in the supports and arms, and the curve of the key 23 will be proportionate to the curve of the peripheral surface of the roller.

When an adjustment is to be made, the studs 24 in the supports I3 are loosened and the lock nut 31 on the screw 29 is backed off slightly. The

collar 35 is then rotated to move the screw 29 forward or rearward, which thus raises or lowers the nose 42 of the former and also moves the arms I! over the keys 23 a proportionate amount.

' -When the desired adjustment is made, the lock nut 31 is again locked against the collar 35 and the studs 24 are tightened to thereby clamp the former in its adjusted position.

With a device of the type decribed, it is thus possible to provide a suitable support for a former to be used under conditions where there is not sufiicient room to provide bearings for each side of the former and which may be moved through a path equivalent to swinging same from the axial center of the web guide roller. The effect of the former mounting in the present structure, therefore, will be equal to that of a mounting which is pivoted on the axial center of the web guide roller.

It will be understood that the invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it is therefore desired that the present embodiment be considered in all respects as illustrative and not restrictive, reference being had to the claims rather than to the foregoing description to indicate the scope of the invention.
